In a final flurry of frantic campaigning on the day of the hotly contested Pennsylvania Primary, both hopefuls knock hard on each other’s campaign slogans in an effort to discredit each other’s bid for the Democrat presidential nomination. “It’s not enough to say ‘Yes we can.’, ” decries New York Senator and recovering duck-and-cover performance artist Hillary Clinton in a direct assault on Barack Obama’s audaciously hopeful refrain, “We have to say how we can.”

Official Clinton campaign sources are reportedly mulling over the 34th change to Clinton’s own campaign slogan to capitalize on the crowd’s warm response to her attack, contemplating a move from “I’m in it to win it.” to “How can we?” This apparent instability of message is chalked up as a strength, mirroring the rapid and revolutionary transformation of society promised by the candidate.

By contrast, staunchly firm and rigidly unwavering in his rock-solid, time-tested and changeless motto “Change we can believe in”, Obama, Senator and Trinity United Church of Christ absentee from Illinois, defended his slogan by noting how new and fresh his politics of bitterness were. “I’m asking Pennsylvanians to believe,” he reaffirms, “in me so they don’t have to cling to guns or religion.”
